I fought Ceaseless Discharge after Quelaag and forgot about him. Three mini-bosses and a puzzle boss, didn't even realize it. I beat it and yea, everything post Anor Londo is kind of disappointing. I only sorta like one and half levels. New Londo wasn't bad. There was only one room that was bad and it was right before the boss and could run through it and Tomb of the Giants was eh. I hated Duke's Archive. Skeleton Archers hiding behind mages hiding behind more archers hiding behind warriors. And the crystal cave just seemed pointless.
